Abstract

Spelling is an important application of braincomputer interface (BCI). However, the visual saccade-independent P300 BCI spellers generally are not suited for widespread use by people who have lost voluntary eye movement due to their poor performance. In this study, we propose a novel P300 BCI paradigm for spelling through auditory-tactile bimodal stimuli. The target number of speller is increased and thus the information transfer rate (ITR) is improved. Specifically, a BCI speller with 36 selectable items was developed by simultaneously and randomly presenting auditory and tactile stimuli from same one of six directions. With six participants, the average simulated online ITR of the bimodal-stimulus-BCI system increased by 30% and 34% compared with the auditory and tactile approach, respectively. These findings suggest the proposed bimodal BCI paradigm is exceedingly efficient, which is promising for achieving quick spelling in visual saccade-independent P300-BCI application.

一种新的基于听觉触觉p300的脑机接口范式

拼写是脑机接口(BCI)的一个重要应用。然而，不依赖于眼跳的P300 BCI拼写器通常不适合那些由于表现不佳而失去自主眼球运动的人广泛使用。在这项研究中，我们提出了一个新的P300脑机接口模式，通过听觉-触觉双峰刺激拼写。增加了拼字者的目标数目，从而提高了信息传输率。具体而言，通过同时随机呈现来自六个方向的听觉和触觉刺激，开发了一个包含36个可选择项目的脑机接口拼写器。在6名参与者中，与听觉和触觉方法相比，双峰刺激-脑机接口系统的平均模拟在线ITR分别增加了30%和34%。这些结果表明，所提出的双峰脑机接口模式是非常有效的，有望在视觉非视扫视的p300 -脑机接口应用中实现快速拼写。
